Antarctic Legged Research Base Crawls Out Of The Snow

Antarctic Legged Research Base Crawls Out Of The SnowOn February 5th 2013, Halley VI Research Station was officially opened.  It is located on the Brunt Ice shelf which is floating on the Weddell Sea.  Construction started in 2005 at a cost of £26 million, by Faber Maunsell and Hugh Broughton Architects who provided the winning design in an architectural design competition held by British Antarctic Survey and RIBA Competitions.

The biggest challenge for engineers in the Antarctic region is perhaps that everything gets snowed under over a period of time. The Halley VI station leaps over this problem, literally. The Pods of the station are mounted on hydraulic legs based on Ski’s. This configuration allows the station to get out of snow and move to a new location and away from the ocean. And that’s not all. The biggest pod is red in color and has a bar, lounges and a pool hall for recreation. It also houses a salad garden and a climbing wall, just so the people working there (about 70 in summers) do not lose their motivation and spirit during their stay.

The Halley VI base station is a true wonder of science and clearly shows that hard work and a bit of creative imagination can go a long way. For more photos, head to the official site.

Scientists describe how bacteria changes gold ions into gold

Old King Midas thought being able to turn anything he touched in the gold was a good deal. However, it turned out having the Midas touch wasn’t such a winning proposition. A certain type of bacteria is able to turn gold ions into harmless gold nanoparticles that accumulate outside of its cells.

The process is a defense mechanism that the bacteria uses because gold ions are toxic. The bacteria is Delftia acidovorans and while science has known about the process, it has only recently been described by researchers. The scientists believe that by understanding and describing the process that it may be possible to one day develop methods to retrieve gold out of the water that carries it.

The process could be used to design sensors able to identify streams and rivers rich in gold. The chemical protein in the bacteria that uses for the Midas-like process is called delftibactin A by the scientists. The bacteria secrete the protein into its surroundings when it senses gold ions. The protein then chemically changes gold ions into particles of gold ranging between 25 and 50 nm across.

Those particles then accumulate near the bacteria creating patches of gold. However, rather than having namesake golden color, the particles of gold created by this bacterial process make flakes that are a deep purple color. The scientists believe that if the delftibactin A is selected for gold it could be useful for gold recovery or as a biosensor.

The 20 Loneliest Outposts At the End of the World

When humanity’s not trying to destroy itself, its steadily redefining its boundaries. Every passing year, we create further-flung outposts in places nature never intended to us to inhabit. Here are the loneliest places mankind has made its bed in search of the unknown, the overwhelming, and the great. More »

Strange flashing star could be twins

Scientists have discovered a strange flashing star floating in space. The star system is dubbed LRLL 54361 and was discovered using the infrared Spitzer Observatory and the Hubble Space Telescope. The most interesting thing about star system is that the star appears to be flashing like a strobe light.

Researchers and astronomers have been investigating the system and believe that the cause of the flashing may be that what they have discovered isn’t a single star, but a newly formed pair of stars. The scientists believe that this pair of stars may be circling each other very closely causing the light to flash like a strobe. The researchers say that the discovery of this flashing star system is important because this is only the third “strobe light” object ever seen.

Astronomers say that the star system is about 950 light years from Earth and that the star produces a pulse of light every 25.34 days. The scientists also note that this particular stellar strobe is the most powerful ever discovered. Scientists are having a difficult time determining the exact source of the strobe phenomenon in the system.

The reason for the difficulty is that the star system is hidden behind a dense cloud of dust and a disc of material. The Spitzer infrared telescope was able to see into the cloud of dust and debris with enough resolution to determine that there were signs of a protostar or a pair of protostars in the system no more than a few hundred thousand years old. A current theory on the source of the flashing is that when the two stars pass close to each other in their orbits the cloud of dust and gas being dragged behind them falls onto the surface of one or both stars causing a flash of light.

Curiosity rover bores into Mars for the first time

NASA’s Curiosity rover, which is currently putzing its way around Mars, has just drilled its way into Martian soil for the first time, making a perfectly cylindrical hole on the surface of the Red Planet. The hole is approximately 0.8-inches deep and about 0.6-inches across. From the photo below, the hole looks much bigger, but it seems NASA only need just a slight sample of the planet’s dirt.

The operation, which NASA calls the “mini drill test,” is just the prequel to a full drilling that NASA will conduct sometime soon. If the drill shavings around the fresh hole pass visual evaluation by the rover’s testing mechanisms, the rover team plans to proceed with the first full drilling in a couple of days.

The mini drill test was performed on a patch of flat rock called “John Klein,” which is the same patch of land that other tests were run, including percussion-only testing and planned sample-collection drilling. The rover team plans to use Curiosity’s laboratory instruments to analyze soil samples and learn about the environmental history, including whether or not life was present at any point in time.

Curiosity has been sitting in an area named Yellowknife Bay for a few weeks now, where it has also discovered that rocks in the area were at one time repeatedly flooded by water sometime in the past. NASA is being extremely careful and going very slowly with their experiments, and they say that full-drilling operations will be the most complex sequence the rover has yet to perform on Mars. Good luck, padawan!

Tiny Internal Explosions Power This Robot’s Amazing Jumping Prowess

For years we all assumed that robots and artificial creatures had to be made of metal and other rigid materials. But there’s now a movement to create soft, squishy bots that use unorthodox power sources like compressed air, and, believe it or not, literal explosions. More »

Reusable Glue Gives You a Mulligan by Unsticking Under UV Light

Researchers at Japan’s National Institute of Advanced Industrial Science and Technology, or AIRT for short, have developed a remarkable new adhesive that can solidify (stick) or liquify (unstick) at room temperature with a blast from a UV light. More »

Intelligent Keyboard-Wide Touchpad Is Smart Enough To Ignore Your Palms

With gesture controls becoming more common in software and apps, it makes sense to maximize the size of a laptop’s touchpad to facilitate more than just a couple of fingers. So researchers at the Korea Advanced Institute of Science and Technology have developed the Longpad, an oversized touchpad that’s as wide as a keyboard and smart enough to ignore the user’s hands when they’re typing.

ABI: Android king of end-of-2013 “1.4 billion smartphone” estimate

This week the folks at ABI have released a study that predicts a massive 1.4 billion smartphones to be in-use by the end of 2013, 798 million of them Android-based. This set of numbers also suggests that Windows Phone will be in around 45 million smartphones while Apple will retain the number 2 spot with 294 million units – iPhones, the lot of them. This study suggests that by the end of this year the world will have 268 million tablets in-use – seem to you like there’s a bit of a difference in the way we use “smart” electronics?

This set of studies is, of course, all based on estimates and analysis, here suggesting that the number of tablets we’ll see by the end of this year represents a massive 125 percent growth over 2012′s final set. Of this 2013 year-end set, 62 percent will be Apple’s hardware while 28 percent will be Android-based. That’s quite the flip-flop compared to how the smartphone universe is trending.

ABI has predicted that 20 million BlackBerry 10 devices will be up and running by the end of 2013 – this boding relatively well for the company that just launched their new operating system here in the first quarter of the year. While some have a less-than-hopeful outlook for the company formerly known as RIM (now just called BlackBerry), even 20 million devices (still less than Windows Phone) is better than none. Windows Phone’s numbers on the end-of-2013 predictions chart shows Microsoft’s mobile OS to be hitting at around 3 percent of the market’s total.

The team at ABI let it be known that the annual smartphone growth rate has been factored in here to get that final 1.4 billion units was a fabulous 44 percent. That number is down from their previous reports showing 2012′s 45 percent growth rate over the year before, this 1 percent change either signifying that we’re reaching a plateau or that we’re simply having a slightly irregular amount of sales change.

iPads (Thanks To The Mini) Were 1 In 6 ‘PCs’ Shipped, Tablets One-Third, And Windows RT Didn’t Even Break 1M: Canalys

ipad-with-ipad-mini

The PC market is fast shifting into a touchscreen world, and Apple is leading the charge. Some new numbers from the analysts at Canalys note that in Q4 of 2012, one in every three PCs shipped was actually a tablet, and that Apple’s iPad accounted for about half of them, or one in every six PCs shipped.

Canalys senior analyst Tim Coulling tells me that by “tablet,” Canalys means any computing device with screen of seven inches or more. By combining PC and tablet numbers — a logical thing to do, given that many are substituting tablet purchases and usage for PC purchases and usage — Canalys figures that worldwide PC shipments are actually on the rise — up by 12% on last year to 134 million units for the quarter. That’s in contrast to figures from Gartner, which in January noted that Q4 PC shipments were down by 5% on last year — without factoring in tablets.

Adding Apple’s iPad sales to its Mac sales puts it into the lead among PC vendors. The company shipped 27 million PC units in Q4, giving it a 20.1% share of the market. The number-two vendor was HP, whose market share is based on its PC prowess. It shipped 15 million PCs, for an 11.2% share of the market. That let it edge just ahead of Lenovo, which shipped 200,000 fewer units.

Still, Android continues to make inroads. Canalys points out that this is the first quarter where Apple’s iPad has not accounted for more than 50% of all tablets shipped — it was 49%, as it happens, with Android accounting for 46%.

Apple’s savior was the iPad Mini: “Apple timed the launch of the iPad mini well,” writes Pin-Chen Tang, Canalys research analyst. “Its success proves there is a clear demand for pads with smaller screens at a more affordable price. Without the launch, Apple would surely have lost more ground to its competitors.” Indeed, that fact may well encourage Apple to look at more sizes and price points for its iOS devices in the future.

Overall, Canalys points out that the tablet market grew by 75% in Q4 to 46.2 million units, and that full-year shipments were 114.6 million units. Given that trend, Lenovo, which has been making some interesting hybrid models incorporating both touchscreen and keyboard features, could well pull ahead of HP if the latter doesn’t make some significant tablet inroads in the next couple of quarters.

Meanwhile, Samsung is at the other end of the spectrum: its strong performance, placing it into fourth place with 11.7 million units (9% market share) is based mostly on the success of its line of Galaxy Tab tablets. It shipped 7.6 million of these in Q4, a rise of 226%.

Dell, which is hoping for a turnaround as a private company, rounded out the top five. Dell’s reputation “continues to fade,” Canalys writes, resulting in a 19% drop in shipments in the quarter. “A turnaround in fortunes is likely to take years,” they note — so just as well that Dell will not have to answer so quickly to the markets for its performance.

As other analysts have pointed out, Windows 8 has so far had little impact on worldwide PC shipments, and an almost negligible impact on tablets — with only 3% of tablets shipped in the quarter based on Windows 8.  That has had a knock-on effect both for Windows and for those who make devices using the OS. “Microsoft’s involvement in the Dell buyout raises eyebrows in the light of its recent aspirations to become a hardware vendor,” Canalys notes. “But it is not likely to solve Dell’s problems as even Microsoft struggles with pads.” Equally difficult was Windows RT, which failed to break even 1 million units at 720,000 shipped. “The outlook for Windows RT appears bleak,” noted Tim Coulling, Canalys senior analyst. He believes the only way out for this is for Microsoft to drastically reduce the licensing price, cutting further into its margins on the product.

Western Europe’s slow economy also continues to weigh things down.

Amazon, selling only tablets and no PCs (yet?), didn’t make the top five but still managed a substantial volume shift. Its shipments were 4.6 million units, almost mirroring Dell’s decline with growth of 18%. With the Kindle Fire now selling in more markets worldwide, it will be interesting to see if Amazon can see a big boost this year or if it will be stymied by Apple and Samsung. For now, international is doing a good enough job to offset some small declines in the U.S., where the launch of the higher-priced Kindle Fire HD not proving to be a runaway success as the initial launch of the Kindle Fire was a year ago.
